摘要
本文选用三乙基铝-乙酰丙酮-水三元催化剂合成了环氧乙烷和环氧丙烷的共聚物,制备了室温电导率较高(5×10^(-5)Scm^(-1)),柔韧性较好的共聚物—NaSCN复合物膜。研究了共聚物组成对聚合物结晶性及对复合物电导率的影响规律,考察了硫氰化钠浓度、成膜条件对复合物室温电导率的影响以及复合物电导率的温度依赖关系。
In this paper, the copolymer of ethylene oxide and propylene oxide was synthesized with catalyst composed of AlET3-Hacac-H2O, and the flexible complex film of copolymer-NaSCN which shows high ionic conductivity (4×10-5Scm-1) at room temperature was prepared. The effect of copolymer composition on its crystallinity and conductivity of complex was studied. The effects of salt concentration and casting solvent on room temperature conductivity of the complex and the temperature dependence of conductivity were performan-ced.
